水循环关键要素遥感反演研究进展OA

The water cycle is a crucial process in the Earth system,profoundly affecting water resource management,climate change response,and eco-environment protection.Remote sensing is the primary means of monitoring key elements of the water cycle on a large scale,and significant progress has been made over the past few decades.This paper reviews the research progress in remote sensing inversion technology for key water cycle movement elements such as evapotranspiration and precipitation,as well as key water cycle storage elements such as soil moisture and water storage.It also identifies the current trends in refined monitoring,proposes directions for technological innovation,and highlights urgent scientific issues that need to be addressed.This review aims to provide references for enhancing the depth and breadth of development and application in the field of water cycle remote sensing.
